1. A radio station for controlling an interfered system signal transmitted using a shared frequency band which an interfered system uses in priority to an interfering system, comprising:

  • a broadcast section that broadcasts load information of the interfered system to a transmitting station in the interfering system;

    an acquisition section that receives predicted interference power, from the transmitting station that calculates the predicted interference power caused in a receiving station in the interfered system by an interfering system signal transmitted using the shared frequency band from the transmitting station;

    an allowable interference level control section that increases an allowable interference level of the interfered system signal transmitted using the shared frequency band, based on the predicted interference power acquired in the acquisition section; and

    wherein the allowable interference level control section increases transmission power of the interfered system signal or decreases a transmission rate of the interfered system signal, so that signal quality of the interfered system signal can be maintained even when the receiving station in the interfered system receives the predicted interference power by the interfering signal.
